Description

Technical Field

[0001] This disclosure generally relates to door panel assemblies, and more specifically, to a bottom mounting plate for door panel assemblies. Background Technology

[0002] Door panels are known for their use in applications such as cabinets, entrance / exit doors, and furniture. One type of door panel is the sliding door panel, which has long been a staple in architectural and interior design, providing an elegant and space-saving solution for room partitions, closets, and various entryways. Traditional sliding door assemblies require the door panel to fit precisely into the rails, a process inherently limited by the fixed width of these rails. Therefore, the door panel must conform to the standardized width of the rails to be properly accommodated within the sliding door assembly.

[0003] Traditional methods for installing door panels in sliding door assemblies have several limitations. First, these methods require the production of door panels with specific widths that match the width of the guide rails, resulting in a lack of versatility. Therefore, without custom design, door panels of varying thicknesses cannot be seamlessly integrated into the guide rails. Furthermore, these limitations directly impact design possibilities due to constraints on material selection and overall design flexibility. Addressing these limitations will not only expand design possibilities but also simplify the installation process of door panels in sliding door assemblies, making sliding doors a more adaptable option for both residential and commercial applications.

[0004] Furthermore, the gaps between the door panels in traditional sliding door assemblies are a long-standing problem. These gaps allow dust, pests, liquids, and other unwanted elements to enter, as well as the enclosed space, compromising cleanliness. Therefore, the threats posed by these gaps not only affect the overall function of the door but also necessitate frequent maintenance and cleaning. Summary of the Invention

[0021] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] This disclosure relates to a door panel assembly including a top mounting plate and a bottom mounting plate for securely mounting a door panel within the assembly. The mounting plates of the door panel assembly disclosed herein not only ensure the structural integrity of the door panel but also ensure precise alignment of the door panel within the assembly based on its thickness. Both the top and bottom mounting plates provide a holistic solution for the seamless operation of the door panel assembly.

[0023] Figure 1 The illustration shows a side view of a door panel assembly 100 mounted on a frame 500. The door panel assembly 100 includes a first door panel 200-1, a second door panel 200-2, and a mounting assembly 600, which includes a top mounting plate 300 and a bottom mounting plate 400. The door panel assembly 100 may include a frame 500 having a top guide rail 104 and a bottom guide rail 106. The top guide rail 104 may be located inside the top edge 102-1 of the frame 500, and the bottom guide rail 106 may be located inside the bottom edge 102-2 of the frame 500. The bottom edge 102-2 may be parallel to the top edge 102-1, thereby making the guide rails 104 and 106 parallel to each other, which ensures that the door panels 200-1 and 200-2 are securely mounted between the guide rails 104 and 106.

[0024] The first door panel 200-1 and the second door panel 200-2 may include top portions 200-1A, 200-2A and bottom portions 200-1B, 200-2B. The top mounting plate 400 may be adapted to be connected to the top portions 200-1A, 200-2A of the door panels 200-1, 200-2, while the bottom mounting plate 300 may be adapted to be connected to the bottom portions 200-1B, 200-2B.

[0025] The top mounting plate 400 can be attached to the top portions 200-1A and 200-2A of door panels 200-1 and 200-2 respectively, allowing precise adjustment of door panels 200-1 and 200-2 along the top guide rail 104. The bottom mounting plate can be attached to the bottom portions 200-1B and 200-2B of door panel assembly 100, allowing precise adjustment of door panels 200-1 and 200-2 along the bottom guide rail 106.

[0026] In one example, the first door panel 200-1 may be the front door of the door panel assembly 100, and the second door panel 200-2 may be the rear door of the door panel assembly 100. It should be understood that the designation of front and rear doors is based on the arrangement of the door panels on the frame, and this designation can be interchanged depending on the arrangement. For the purpose of continuing to explain this disclosure, the first door panel 200-1 will be considered as the front door of the door panel assembly 100, and the second door panel 200-2 will be considered as the rear door of the door panel assembly 100.

[0027] In one embodiment, the top mounting plate 400 may be adapted to slidably connect the first door panel 200-1 and / or the second door panel 200-2 to the top guide rail 104 of the door panel assembly 100. Similarly, the bottom mounting plate 300 may be adapted to slidably position the first door panel 200-1 and / or the second door panel 200-2 in the bottom guide rail 106 of the door panel assembly 100, based on the thickness of the door panels 200-1 and 200-2 in the bottom guide rail 106. Thus, each of the mounting plates 300 and 400 may be adapted to guide the first door panel 200-1 and / or the second door panel 200-2 within the door panel assembly 100 and secure the first door panel 200-1 and / or the second door panel 200-2 within the door panel assembly 100.

[0028] According to this disclosure, the mounting plates 300 and 400 of the door panel assembly 100 are adapted to adjust the door panels 200-1 and 200-2 in the door panel assembly 100 based on the thickness of the door panels 200-1 and 200-2. The mounting plates 300 and 400 help to provide enhanced adjustability, ease of installation, and stability for the door panels 200-1 and 200-2 in the guide rails 104 and 106 of the door panel assembly 100. Therefore, the door panel assembly 100 allows the door panels 200-1 and 200-2 to slide smoothly and adjustably within the guide rails 104 and 106.

[0029] In one embodiment, additional door panels (not shown) may be added, each having a designated mounting assembly 600 including a top mounting plate and a bottom mounting plate. For example, the additional door panel may be slidably disposed between an additional top guide rail (not shown) and an additional bottom guide rail (not shown). The additional top guide rail and the additional bottom guide rail may be adjacent to the top guide rail 104 and the bottom guide rail 106, respectively. Furthermore, the additional door panel may include the mounting assembly 600 having a top mounting plate coupled to the top portion of the additional door panel. The bottom mounting plate may be coupled to the bottom portion of the additional door panel.

[0030] This disclosure primarily focuses on the structure and function of the bottom mounting plate 300 of the door panel assembly 100, such as... Figure 2 As also shown in Figure 4c. Specifically, Figure 2 The lower portion of the door panel assembly 100 is illustrated, showing a detailed view of the bottom mounting plate 300 for the first door panel 200-1 and the second door panel 200-2. In one embodiment, the bottom mounting plate 300 may include a bottom mounting plate 300 for the first door panel 200-1 and a bottom mounting plate 300 for the second door panel 200-2. Specifically, Figure 3A The illustration shows a perspective view of the bottom mounting plate 300A used for the first door panel 200-1. Figure 3BThe diagram shows an exploded view of the bottom mounting plate 300A used for the first door panel 200-1. Specifically, Figure 4A The illustration shows a perspective view of the bottom mounting plate 300B used for the second door panel 200-2. Figure 4B The illustration shows a front view of the bottom mounting plate 300B used for the second door panel 200-2. Figure 4C An exploded view of the bottom mounting plate 300B used for the second door panel 200-2 is shown.

[0031] Now we will combine Figure 2 The construction aspects of the bottom mounting plate 300 are explained in detail with reference to Figures 3a to 4c. The bottom mounting plates 300A and 300B may include a mounting frame 302, a roller mounting base 324, and a height adjustment mechanism 320. The mounting frame 302 may be adapted to be connected to the bottom portions 200-1B and 200-2B of the first door panel 200-1 and / or the second door panel 200-2. The mounting frame 302 may also include a base 302A having a first hole 328 and a pair of arms 302B extending downward from the end of the base 302A.

[0032] In one embodiment, the bottom mounting plate 300B for the second door panel 200-2 may be adapted to adjust the position of the second door panel 200-2 in the guide rail based on the thickness of the second door panel 200-2. In another embodiment, the bottom mounting plate 300A for the first door panel 200-1 may optionally be adapted to adjust the position of the first door panel 200-1 in the guide rail based on the thickness of the first door panel 200-1, as shown in Figures 3a and 3b.

[0033] Referring now to Figures 4a to 4c, in order to adjust door panels 200-1 and 200-2 based on their thicknesses, bottom mounting plates 300A and 300B may include a bracket 308 having a first segment 308A and a second segment 308B. The first segment 308A can be coupled to the base 302A of the mounting frame 302. A threaded member 334 can pass through a second hole in the base 302A to engage the second segment 308B of the bracket 308 to the base 302A of the mounting frame 302. The threaded member 334 can rotate about its axis, thereby allowing adjustment of the position of the bracket 308 relative to the base 302A. The adjustment of the position of the bracket 308 can be based on the thickness of the second door panel 200-2. A locking unit 314 can be added to secure the bracket 308 to the mounting frame 302 by locking the threaded member 334 after the adjustment of the bracket 308 is completed. Once the bracket 308 is locked together with the mounting frame 302, the base 302A of the mounting frame 302 can be covered with a cover 332 to prevent dust or any impurities from entering the bottom mounting plate 300B. In one embodiment, the mounting frame 302 can be covered with a rear cover 336 to provide structural integrity. During movement of the mounting frame 302, the rear cover 336 moves with the mounting frame 302, while the bracket 308 remains stationary.

[0034] Furthermore, the roller mount 324 may include a housing 310, a roller 312, and a pair of springs 322, the roller 312 being rotatably mounted in the housing 310, and the pair of springs 322 being mounted between the housing 310 and the mounting frame 302. The roller mount 324 may be slidably coupled to the mounting frame 302 and adapted to slide between a pair of arms 302B, which allows the roller mount 324 to be securely mounted in the bottom guide rail 106 of the door panel assembly 100.

[0035] Referring now to Figures 3a to 4c, the bottom mounting plates 300A and 300B are adapted to adjust the overall height of the door panels 200-1 and 200-2. To assist this, a height adjustment mechanism 320 can be disposed on the mounting frame 302 and adapted to allow the roller mounting seat 324 to slide relative to the mounting frame 302. The height adjustment mechanism 320 may include a threaded member 304 having a body 304-1 and an end 304-2, the body 304-1 being disposed in a first hole 328, and the end 304-2 being adapted to push the roller mounting seat 324 to slide between a pair of arms 302B, thereby facilitating the adjustment of the overall height of the bottom mounting plates 300A and 300B.

[0036] The reduced need for extensive modifications during installation and increased maintenance efficiency contribute to cost savings for residential and commercial applications. Furthermore, the adaptability of the door panel assembly 100 provided by the bottom mounting plates 300A and 300B minimizes the possibility of costly customization requirements. In addition, the bottom mounting plates 300A and 300B not only address existing limitations but also enhance the overall functionality of the door panel assembly 100. The adaptability of the door panel assembly 100 provided by the bottom mounting plates 300A and 300B enables the use of more sustainable materials and designs, which helps reduce the environmental footprint of architectural and interior design projects.

[0037] Furthermore, the mounting assembly 600 may also include a locking unit 318 positioned on a portion of one of the pairs of arms 302B. In one example, the locking unit 318 may include, but is not limited to, a nut. The locking unit may be adapted to securely lock the roller mount 324 to the pair of arms 302B after the roller mount 324 has been slidably mounted in the bottom guide rail 106 of the door panel assembly 100. Additionally, a locking unit 314 may be provided for locking the bracket 308 to the mounting frame 302 after an adjustment process.

[0038] In one embodiment, the bottom mounting plate 300B may include a pair of measuring bars 316 extending orthogonally from the surface of the bracket 308 toward the mounting frame 302. Each of the pair of measuring bars 316 may include a plurality of scales 316A adapted to indicate linear displacement of the bracket 308 along an axis when the bottom mounting plate 300B is adjusted into the bottom guide rail 106 based on the thickness of the door panel 200-2.

[0039] Furthermore, the bottom mounting plate 300B may include a cleaning structure 306 for cleaning the guide rail 106 of the door panel assembly 100. In one example, the cleaning structure 306 may include, but is not limited to, a brush. During the sliding of the door panels 200-1 and 200-2 within the guide rail 106, the cleaning structure may be adapted to sweep impurities out of the guide rail 106. This cleaning of the guide rail 106 can contribute to the lifespan of the door panel assembly 100 and its seamless operation.

[0040] In one embodiment, even after accommodating door panels 200-1 and 200-2 based on their thickness, it may still be necessary to seal any gaps between door panels 200-1 and 200-2 for cleaning purposes. To seal these gaps, door panel assembly 100 may include a dustproof strip 326 disposed between the first door panel 200-1 and the second door panel 200-2 and / or between the first door panel 200-1, the second door panel 200-2, and any additional door panels, such as... Figure 5 shown in . Specifically, Figure 5 The illustration shows a dustproof strip 326 positioned between the first door panel 200-1 and the second door panel 200-2. The dustproof strip 326 is designed to prevent impurities and pests from entering between the adjacent door panels. By effectively sealing the gap between the door panels 200-1 and 200-2, the door panel assembly 100 eliminates entry points for dust, pests, liquids, and other unwanted elements. This enhancement not only improves cleanliness but also enhances the overall functionality and lifespan of the door panel assembly 100.

[0041] The bottom mounting plates 300A and 300B of this disclosure allow for the accommodation of door panels 200-1 and 200-2 with varying thicknesses. Therefore, the bottom mounting plate 300 facilitates the possibility of architects and interior designers selecting from a wider range of door panels and creating customized solutions to meet diverse needs regarding the guide rails 104 and 106. Unlike traditional systems, the bottom mounting plates 300A and 300B disclosed herein simplify the process of adapting sliding doors to any existing furniture or opening. The ability to accommodate door panels 200-1 and 200-2 of varying thicknesses reduces the need for costly structural modifications.

[0042] Furthermore, the reduced gap between door panels 200-1 and 200-2 makes it easier to maintain and clean door panel assembly 100. Because the area for dust and debris accumulation is reduced, door panel assembly 100 is more user-friendly and requires less frequent maintenance, thus saving time and resources.

[0043] While specific language has been used to describe this disclosure, it is not intended to impose any limitations. As will be apparent to those skilled in the art, various working modifications can be made to the methods to achieve the inventive concepts taught herein. The accompanying drawings and the foregoing description provide examples of embodiments. Those skilled in the art will understand that one or more described elements can be combined into a single functional element. Alternatively, some elements can be separated into multiple functional elements. An element in one embodiment can be added to another embodiment.
